The process of forming an angle geometrically is called the formation of an angle.

Every angle is formed by a procedure in geometry. The formation of an angle plays vital role to measure the angle.

Similarly, it is also useful to determine the sign (or sense) of the angle.

There are two different geometric theories to form angles geometrically.

An angle is formed when a straight line is rotated from its initial position to final position in either clockwise or anticlockwise direction.

An angle is formed geometrically when two straight lines are started from a common point on the plane.
